The data below are readings taken from three
wearable devices over a 30 day period for one individual: The Basis peak, The
fitbug Orb and the Xiaomi MiBand.

The
individual weighs 72 KG and is 174cm tall

All
devices were worn on the left wrist (the individual is right handed)

Some
basic statistics are also given: correlation between each device for
measurments such as "daily steps taken", "calories burnt"
and sleep data

Generally
the devices differ by a fair amount but correlate well for daily steps.

Sleep
data was not consistent (correlation is 0.53 for example between the fitbug
and the basis peak)

We
currenly have no validation data for the heart rate readings taken from the
Basis Peak.

The
data below are:

-
Total steps taken per day

-
Total number of minutes for sleep (split between light, heavy, REM where
available)

-
Calories burnt per day (the miband only gives calories burnt during periods
of "activity")

-
Average heart rate over differing periods of each 24 hour period
